How to Fix Minecraft Low FPS on High-End PC in 2023

Lowering the graphics settings, disabling VSync, or allocating more RAM can improve FPS.

Minecraft players are in thousands yet they complain that Minecraft Java Edition is very unoptimized. Players with high-end systems running the latest CPUs and high-end GPUs like RTX 3070 ti and RTX 3090 are complaining that they get Low FPS despite having a High-End PC running Windows 10 / Windows 11.

There are many reasons for Minecraft’s low FPS even on a good PC. Minecraft Java Edition players suffer from extreme optimization problems and for that reason, lowering your in-game graphical settings might help. The PC’s having older hardware can’t brute force performance. So, allocating Minecraft more RAM can also improve FPS drastically on a High-End PC. Nvidia’s Control Panel and Windows Power Settings set to Power Saving Mode can also reduce your FPS in Minecraft even on a decent PC.

If you are among those who’re running Minecraft on a high-end PC and still get low FPS then try the fixes we have mentioned below. You don’t need to apply all these fixes instead just go through them one by one and see if they work for you.

How to Fix Minecraft Low FPS on High-End PC

1. Lower Minecraft’s Graphics Settings

Minecraft has a very unique art style and graphic design. However, these graphics do not require a High-End PC but due to the fact that it is unoptimized, players report that lowering their graphical settings improved their FPS. Adjust Minecraft’s graphics settings according to the picture given below.

Make sure to lower Render Distance in particular as it is very taxing on the CPU. It may also be that Minecraft is simply FPS-locked so set Max Framerate to Unlimited to unlock the FPS.

2. Disable VSync

Disabling VSync fixes the Minecraft Low FPS on a High-End PC according to multiple sources. In order to achieve what VSync did after disabling it you can lock FPS to your display’s refresh rate.

If you are facing Low FPS on a High-End PC then we recommend you switch over to Minecraft Windows Edition from Java Edition.

As an alternative you can download Driver Easy and it will automatically find all new drivers for you to install on the click of a single button.

13. Reinstall Minecraft

If nothing else works then try reinstalling Minecraft to fix the Low FPS on High-End PC problem. Minecraft is relatively small in size so downloading it again should neither take a lot of time nor a lot of data on your end. It is worth a try so go ahead and uninstall Minecraft through Add or Remove Programs menu. You can then download it again from Minecraft’s official website.
